In addition, the present invention includes means for attaching a container to the vehicle at a corner of the vehicle, and allowing a vertical opening in the container to be fully accessible as the container is moved from a location adjacent one side of the vehicle to a location adjacent another side of the vehicle. Preferred embodiments of the invention include a double pivot structure connecting a container, such as an exterior kitchen, to a RV, where the front of the container serves as a kitchen counter when opened, and provides access to a stove and refrigerator. In those preferred embodiments, the exterior kitchen can be selectively locked into a variety of positions, rotated with respect to the corner of the vehicle, and vertically supported on the vehicle side wall and/or the ground, without manual lifting of the container.

This application claims priority from U.S. Provisional Application Ser.No. 62/245,731, filed on Nov. 13, 2015, entitled Recreational Vehiclewith Kitchen Facilities, to the fullest extent permitted by law.

BACKGROUND OF THE INVENTION

The present invention relates to exterior storage and utility facilitiesfor use with vehicles. More specifically, this invention relates to acontainment system for recreational vehicles (such as travel trailersand motorhomes) which can be selectively located for optimal utility onthe rear or sides of a vehicle without detachment from the vehicle whilerepositioning. This containment system is especially suited for holdingand securing exterior kitchen applications.

Previously, various arrangement have been suggested for attachingcontainers or accessories to the exterior of a vehicle. In somearrangements, the item was removable from the vehicle by lifting theitem off of a support structure, such as a latch or rail, and thenstored within the vehicle or elsewhere. An example of this would bepropane bar-b-que grills which are attached to the side of a traveltrailer and coupled to a propane source when in use, and then detachedfrom the trailer and the propane source for cleaning and/or storageelsewhere. While certainly useful for outdoor cooking, these itemsrequire the user to manually lift and carry the item and to visuallyalign it with a support structure when coupling to the vehicle.Accordingly, such arrangements are of limited application when the itemis heavier and/or when sufficient structural support for the item weightand/or size of the item requires more complicated alignment and/orcoupling to the vehicle. Also, larger and heavier items requireconvenient storage locations when not in use.

Previously, larger containers and accessories have been attached to therear of a vehicle for storage and have been removable for use. Exampleof this would be tool boxes or coolers mounted directly or indirectly tothe hitch of a vehicle. These arrangements have often provided aconvenient storage space, but they still require the user to manuallylift the item out of or off of the hitch connection. Further, wheredirect connection is made to the vehicle hitch, the user is alsorequired to align the connection components, often with visualimpairment of the connection location, due to the size of the container,often while still manually holding or lifting the container. Indirectconnection arrangements to the vehicle hitch often avoid the alignmentdifficulties, but at the expense of separate and additional structure,expense, and weight. Further, since many vehicle users desire to towtrailers with the hitch, use of the hitch for a container necessarilyprevents concurrent towing. In addition, where the vehicle has atailgate or rear ramp door, mounting a container to the hitch for eitherstorage or use would block operation of the vehicle tailgate or rampdoor.

Previously, it has been suggested to mount certain vehicle accessories,such as spare tires, on a swingable arm at the rear of the vehicle. Sucharms are, for example, mounted to the side of the rear wall of thevehicle, over and/or under the rear lights, so that the tailgate can beraised and lowered when the arm is swung out of the way. They can alsobe mounted to the end portion of the vehicle bumper without attachmentto the vehicle body. However, these arms are typically mounted via asingle pivot point, intending a field of motion of 90 to 180 degrees atmost. Typically, the pivot axis does not extend away from the vehiclepast the plane of the vehicle side, so as to avoid reduction inaerodynamic characteristics of the vehicle and/or to keep overallvehicle width from expanding. Further, in each of these arrangements,the accessory typically needs to be manually lifted from the supportstructure and carried by the user, in order to be used.

Previously, methods have been proposed for mounting various containersto a vehicle which allow the container to be accessed or used at variouslocations and orientations with respect to the vehicle by means ofpivoting structures connected to a vehicle. However, these structurestypically the require the container to be accessed only through its topsurface, which is maintained in the same horizontal plane in alllocations and orientations of container use. It is often desirable toaccess a container through one or more sides or its front face,especially where it would be advantageous to have the side or front facefold down to be a usable surface, and/or where the objects stored withinthe container tend to be heavy or bulky.

Also, previously, various structures have been proposed to allow forexterior kitchens and/or entertainment systems in recreational vehicles(“RVs”). Such kitchens can include sinks, stoves, refrigerators, and/orcounter space for food preparation. Such entertainment systems caninclude televisions, video recording and playback devices, and variousstereo music components. In certain instances, a slide-out box has beenused having a self-contained kitchen or entertainment system which isaccessible from the exterior of the recreational vehicle when the box isopened and/or extended from the vehicle. However, when the exteriorkitchen or entertainment system is not being used, the slide-out box is,for example, retracted into the vehicle (to keep the appliances thereinsecure) and takes up floor space within the vehicle. Moreover, slide-outmechanisms tend to be expensive and require greater maintenance andinstallation work. In other instances, the kitchen or entertainmentsystem is disposed in a compartment formed in the sidewall of therecreational vehicle, accessible through an exterior door or hatch.These are often less costly than a slide-out box arrangement, but stilltake up floor space in the recreational vehicle, both when being usedand when not being used.

In each case, the floor space used by prior exterior kitchen orentertainment systems require careful planning and orientation withrespect to the rest of the structure and function of the vehiclefeatures. It is especially difficult, for example, to place such kitchenor entertainment system compartments at the rear of “toy hauler” typesof travel trailers, due to “garage” width requirements. Moreover, unlessthe recreational vehicle was designed for the exterior kitchen orentertainment system at the outset, it is especially difficult toretrofit an exterior kitchen or entertainment system to pre-existingrecreational vehicles using these prior arrangements.

In addition, recreational vehicles are typically used in a wide varietyof applications with differing spacial and orientation constraints. Forexample, in a given campground, the vehicle may need to park with asignificantly sloping surface on the side of the vehicle or with treesin close proximity to the vehicle side, making use of an exteriorkitchen on that side undesirable. In those situations, the rear of thevehicle may be preferable for the exterior kitchen location, sincepresumably the vehicle was driven over a sufficiently level surface tocome to that location. In other situations, inclement weather may makelocation of the exterior kitchen on the side of the vehicle, under anawning covering the vehicle door, more desirable than in an exposed rearlocation. Also, since bar-b-que grills are often used in connection withrecreational vehicles, it is desirable to have exterior kitchens capableof a wide variety of facing orientations, in order to facilitate thecooking process in conjunction with grill use. Further, it is sometimesadvantageous to allow exterior cooking components to be fully removablefrom the recreational vehicle, for use at a location more remote fromthe recreational vehicle and/or to facilitate cleaning and maintenance.Thus, an ideal exterior kitchen arrangement would be able to accommodatesuch changes in location. However, the prior slide-out and compartmentformed arrangements typically allow only a single, fixed location ofuse.

Similar disadvantages and concerns arise when attempting to use otherequipment and supply containment systems for recreational vehicles, suchas tool boxes and specialty equipment storage and use. Accordingly, itis an object of the present invention to provide improved arrangementsfor exterior storage and use of containment systems for vehicles. Morespecifically, objectives of the present invention include providingexterior mounting of containers to vehicles which is:

-   -   a. less costly to manufacture, install, and/or to maintain,    -   b. more versatile in mounting location and available range of        use locations,    -   c. readily adapted for use with RV exterior kitchens,    -   d. readily shifted for use at the rear and the side of a        vehicle, without manual lifting,    -   e. capable of supporting significant loads for extended periods        of time,    -   f. not an encumbrance to vehicle floor space, and    -   g. readily retrofitable to existing vehicles.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Several different embodiments of the present invention are illustratedin the drawings. In general, FIGS. 1-14 illustrate one embodiment, FIGS.15-18 illustrate another embodiment, and FIGS. 20(a-c) illustrate yetanother embodiment. FIGS. 19(a-f) illustrate ranges of orientation forgeneric embodiments of the present invention, including these threerepresentative embodiments. The numbering in the figures is consistentacross corresponding components in each of the embodiments.

Referring to FIGS. 1 and 2, a kitchen facility 10 for a recreationalvehicle generally includes a storage unit 20 (or container) and amounting structure 30. In the embodiment shown, storage unit 20generally includes a first or front side 21, a second or rear side 22, athird side (or right side) 23, a fourth side (or left side) 24, a bottom25 and a top 26 defining an interior space 27. First side 21, secondside 22, third side 23, and fourth side 24 are, for example, formed soas to extend above top 26 and form a wall 28 thereabout. A door 29 issecured, for example, to bottom 25 by one ore more hinges (not shown),of a conventional construction. In this manner, door 29 may beselectively pivoted up or down to close or permit access to interiorspace 27. Although not shown in the present embodiment, kitchenfacilities 10 may be provided with a locking or latching mechanism tosecure door 29 in a close position. Also, storage unit 20 may, forexample, be provided with collapsible braces or legs of conventionconstruction, which selectively extend from bottom 25 to the ground uponwhich the recreational vehicle rests, in order to provide additionalsupport for the storage unit when it is positioned away from the rearwall 91 of the recreational vehicle. Similarly, door 29 may be formedwith conventional stops to limit its downward motion to a horizontalplane when opened.

Bracket 80 is a generally L-shaped member having holes 80A therein forsecuring bracket 80 to a recreational vehicle as described below.Bracket 80 is connected at a first end 81 to bracket 60. Bracket 80further includes a pair of latch catches 82 (FIG. 2A) that extendthrough slots S in rear side 22 of storage unit 20 when storage unit 20is in the stowed position as described below.

Referring to FIGS. 1 and 1C, two spring loaded slam latches 100 (one ofwhich is shown) are secured to the interior of storage unit 20 on rearwall 22 thereof positioned above slots S such that a spring loadedlatching members 101 extends at least partially in front of slots S. Inorder to secure storage unit 20 to bracket 80, unit 20 is simply pushedtoward bracket 80 such that latch catches 82 extend through slots Suntil latching members 101 clear the openings therein and engage latchcatches 82. Referring to FIGS. 1 and 1B, storage unit 20 is providedwith a pivoting latch release 102. In order to release latching members101 from latch catches 82, a user simply pivots release 102 upward whichdraws latching members 101 upwardly through a pulley and cable mechanism(not shown) so as to disengage latch catches 82. Other latch releasemechanisms could also be utilized.

FIG. 3 shows kitchen facility 10 secured to a recreational vehicle 90having a rear wall 91 and a side wall 92. This is accomplished bypositioning bracket 60 on a corner of recreational vehicle 90 betweenrear wall 91 and sidewall 92, positioning bracket 80 against rear wall91 and inserting bolts, screws, rivets or other fasteners, through holes61 and bracket 60 and holes 80A in bracket 80. In FIGS. 3-6, storageunit 20 is positioned such that rear side 22 is positioned against rearwall 91 of recreational vehicle 90 with latch members 101 engaged inlatch catches 82 to hold storage unit 20 in place. As shown in FIG. 4,door 29 of storage unit 20 may be provided with supports 29B whichassists in supporting door 29 when it is in the open position shown inFIGS. 5-14.

Kitchen facilities 10 further include a cooking unit 40 and a storagearea 50. Cooking unit 40 can be any of a number of devices including agas cooktop, electric grill, griddle or other device on which food maybe heated or cooked. In the embodiment shown, cooking unit 40 isconnected to a slide mechanism 41, which is in turn connected to bottom25 of enclosure 20, so as to permit cooking unit 40 to slide in and outof interior space 27.

Storage space 50 may be provided with shelving or other structures forstoring food, cooking utensils and other items and/or a second door witha latching mechanism. Alternatively, storage space 50 may be providedwith a refrigerator.

Mounting structure 30 generally includes a first bracket 60, a pivot arm70, a second bracket 80 and two pairs of first mounting brackets 90.Bracket 60 is a generally L shaped member having a plurality of holes 61therein for securing bracket 60 to a recreational vehicle as describedin greater detail below. A second pair of mounting brackets 62 areconnected to and extend from bracket 60 so as to support a pair of pinsP about which pivot arm 70 rotates at one end.

Pivot arm 70 generally includes a first vertically extending member 71,a first horizontally extending member 72, a second vertically extendingmember 73 and a second horizontally extending member 74. Two brackets71A are connected to first vertically extending member 71 and rotateabout pins P captured by brackets 62. The vertical axis extendingthrough these pins P form a first pivot location PL1.

Horizontally extending member 72 is secured at its ends to the upperends of first vertically extending member 71 and second verticallyextending member 73. Two brackets 73A are secure to second verticallyextending member 73 and rotate about pins P captured between bracketpairs 90. Bracket pairs 90 are secured to rear side 22 of storage unit20.

FIG. 6 shows kitchen facilities 10 with door 29 in the open position andcooking unit 40 extended on slide mechanism 41. FIGS. 7 and 8 illustratekitchen facilities 10 with storage unit 20 rotated about pivot locationPL1 such that rear side 22 is generally parallel with sidewall 92 ofrecreational vehicle 90. FIGS. 9 and 10 show kitchen facilities 10 withstorage unite 20 rotated about first pivot location PL1 such that thirdside 23 is generally parallel with sidewall 92 of recreational vehicle90. FIGS. 11 and 12 show storage unit 20 rotating about both pivotlocations PL1 and PL2 such that it can be positioned such that rear side22 is generally parallel with sidewall 92 of recreational vehicle 90, asshown in FIGS. 13 and 14.

FIGS. 15-18 show another preferred embodiment of the present invention,differing from the previously described embodiment in certain features.Accordingly corresponding numbers are used in the figures between thetwo embodiments, where appropriate. In FIGS. 15-18, storage unit 20 is,for example, formed from powder coated metal into a generallyrectangular container which is accessible through door 29. A hinge, 29 aattaches door 29 to storage unit 20 in a conventional manner, andconventional stops 92 b are used to limit the downward motion of door 29to a generally horizontal plane. Thus, door 29 can serve as a counterspace or working area for food preparation and the like when it isopened. Storage unit 20 is formed without wall 28 in this embodiment,allowing top 26 to function as a counter space or working area withoutperipheral limitations. In general, door 29 is formed in a verticalplane, but that vertical plane changes location and orientation asstorage unit 20 is moved about the pivot location(s) of then mountingstructure. Alternative mounting structures are within the scope of thepresent invention, having two or more pivot locations or one pivotlocation on a sliding channel, as described further herein. However, thecommon feature of these mounting structures, and one of its importantfunctions is to allow the vertical plane of door 29 to be oriented forthe door to freely open regardless of whether the storage unit is on therear of the vehicle or the side of the vehicle, and without having toremove the storage unit from the vehicle. Thus, the user is not requiredto lift the storage unit to position it around the vehicle.

Also shown in connection with FIGS. 15-18 are side bumper 100, which isplaced on sidewall 92 so as to protect the sidewall from inadvertentimpact with storage unit 20, and electrical outlets 102 to allowelectric power to appliances stored within storage unit 20. In FIG. 17,storage unit 20 is formed with a bracket 104 which is received byhorizontally extending member 72 when storage unit 20 is to be heldimmobile with respect to member 72, and locking pin 106 is used to thensecure member 72 to bracket 104. Locking pin, is, for example, formed asa conventional cylindrical pin passing through member 72 and bracket104, and tethered to member 72 by wire 108. Similarly, a conventionalpin 110 and slot 112 locking arrangement can be formed with respect tobrackets 71A and pins P to selectively secure storage unit 20 intopre-set rotational positions about pins P. Alternatively, variousconventional locking structures, such a ratchet and pawl, or the likecan be used to selectively control the rotation of storage unit 20 aboutits rotational axis or axes. In FIG. 18, wiring 114 for DC electricpower to storage unit 20 and/or its contents is provide through, forexample, the second, lower horizontally extending member, and into thecorner of rear wall 91 and sidewall 92. Such DC power, could, forexample, be used to provide LED lighting in connection with the storageunit, using conventional LED elements.

In these embodiments, the present invention is characterized by having acorner pivot structure for the storage box which extends outward awayfrom the plane of the vehicle walls at either the side or the rear ofthe vehicle. Thus, the storage unit is able to pivot through an arc ofapproximately 270 degrees (in the horizontal plane, in the illustratedembodiment). The second pivot location allows storage unit 20 toadditionally pivot through an arc of approximately 180 degrees (in thehorizontal plane, in the illustrated embodiment). Thus, door 29 remainsaccessible regardless of which side of the vehicle the storage unit isbeing used on, and regardless of which direction of orientation isdesired for that door, front, back, left or right opening. Stateddifferently, the mounting structure shown allows the vertical plane ofdoor 29 to be rotated through an arc of approximately 360 degrees, eventhough any single pivot location used in the structure has a smaller arcof motion. However, the present invention is not limited merely tomounting structures having two pivot points or hinges and pivot points.For example, FIG. 20(a) show another embodiment of the present inventionwherein storage box 20 is formed with at least one C-channel 120 on itsrear side, which receives therein a pivot pin 130, mounted to extendfrom the corner of a vehicle 140. Working in cooperation, pivot pin 130allows storage unit 20 to slide along C-channel 120 through an arch of270 degrees, keeping door 29 fully accessible at all times. It is alsopossible to achieve the desired motion of the present invention with amounting structure having three or more pivot points, arranged forexample, to allow a more compact collapsed structure when the storageunit is positioned adjacent a vehicle wall. In each case, the storageunit can maintain door accessibility as it is moved, without lifting,between two substantially orthogonal walls of a vehicle.

Further adaptations of the present invention include adding aconventional lift assist device (motor driven, pneumatic strut, orspring assist) to allow the storage unit to slide up and down therotational axis of pivot location PL1. In this way, the storage unit canbe rotated not just to toward the left side wall, but also to theopposite or right side wall of the trailer and, in the elevatedposition, door 29 would be immediately accessible to users of aconventional ramp door patio on the RV, as shown in FIG. 19 b.

Also, in further embodiments, storage unit 20 can be formed to bereadily removable from pins P, such that the storage unit can be liftedoff of the vehicle and used at a remote location, as shown in FIG. 19 f.

The storage unit of the present invention has been described andillustrated in part in connection with kitchen facilities, but is alsosuitable for use with entertainment systems, tools, special equipment,and a variety of other exterior devices which the user may find to bedesirable to store on the exterior of a vehicle, such as an RV. Forexample, if a portable generator was mounted within storage unit 20,that arrangement could provide a number of significant advantages,compared with conventional internal RV generator mounting. Also, anotheradvantage of the present arrangement is that the storage unit's locationat the rear of the RV, especially in connection with toy hauler types ofRVs, can provide a measure of additional security against ramp doorintrusion, without loss of towing functionality.

Although the present invention has been described and illustrated abovein connection with certain embodiments, that is by way of illustrationand example only. It will now be readily apparent that numerousadaptations and modifications of the present invention are contemplated.Accordingly, the spirit and scope of the present invention are limitedonly by the terms of the following claims.
